PCM2707C: Audio Encoder IC application

Lydia Chen
Prodigy 40 points

Part Number: PCM2707C

Hello!

I'm Lydia, a new sales intern from Hsinchu, Taiwan office.

I have a customer requesting an Audio Encoder IC which is able to support four inputs (4*DMIC),
and the output could be I2S or USB or other Interface to SoC.

I wonder if there is any solution to this application. 

Thank you!

    Hi, Lydia,

    We have some devices which support 4 DMIC inputs, like the PCM1865 or PCM1864. These devices are capable of recording audio from digital mics and stream it over an audio serial interface which can be configured with different formats. For example, the four channels can be streamed over a single output in TDM format, but if I²S is supported only, the PCM1865/4 is capable of supporting two I²S stereo outputs.

    Unfortunately, we don't have  a device with 4×DMIC input and USB output.

    Best Regards,
